Good observation, but I did not provide you with enough details. The ICs are wrapped in foil, not visable in the photo. The 6-pin IC has to be from something else, he had various unassembled kits, stuffed into the same bag. The XTALs are there. I need to do an inventory, but first...
I searched for a manual for this. Came up with some, but my board is slightly different from all the manuals I found online. I just joined the SWKits on groups.io. Will be posting there to see if I can come up with the correct manual. Interesting little project.

The 28 pins could just be quantity 7 of the 8 pin ICs up against one another.
